What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that stores URLs, text, contact information, Wi-Fi credentials, and more. Originally developed for automotive manufacturing in Japan, QR codes are now used worldwide for marketing, payments, ticketing, menus, and contactless information sharing. Smartphones can scan QR codes instantly with their camera-no special app needed on most devices.

QR Code Best Practices
- High contrast - Use dark QR on light background (or vice versa) for reliable scanning
- Size for print - Minimum 2×2 cm (0.8×0.8 in); larger is better for distance scanning
- Test before printing - Always scan your QR code before mass production
- Add context - Include text like "Scan for menu" or "Scan to connect" near the code
- Mobile-friendly URLs - Ensure linked pages work well on mobile devices
- Error correction - Use H (30%) for print or damaged surfaces; M (15%) is fine for digital use
